Preparation and Storage
Background: Pentraxin 2/SAP
Pentraxin or Pentraxin 2 (PTX2), also known as Serum Amyloid P component (SAP), is a secreted serum glycoprotein belonging to the pentraxin superfamily. Pentraxins have a characteristic pentagonal discoid arrangement of five non-covalently bound subunits and bind a variety of molecules in a calcium- dependent lectin-like manner through a pattern-recognition-binding site. PTX2 is a major acute-phase protein and may function as an opsonin for a variety of ligands. PTX2 also associates ubiquitously with all amyloid deposits implicated in diseases including Alzheimer's and prion diseases, type 2 diabetes and various systemic amyloidoses.
Assay Procedure
Refer to the product- Prepare all reagents, standard dilutions, and samples as directed in the product insert.
- Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
- Add 50 µL of Calibrator Diluent to each well.
- Add 50 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 3 hours on a horizontal orbital microplate shaker.
- Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.
- Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 1 hour on the shaker.
- Aspirate and wash 5 times.
- Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.
- Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
